Abstract: Nowadays the inconsistent structure and incompatibility with different locating devices of wireless locating application have dramatically slow down the wireless locating application development life cycle and maintenance.Application framework abstracts the common elements of wireless locating applications and helps to improve software reuse and shorten the development lifecycle.In this paper，a wireless locating application framework which supports data fusion of various locating devices is proposed，aiming to separate business logic from underlying locating platform and standardize the structure of wireless locating application.Besides，an instance of this framework is given，core techniques are introduced，the framework’s effectiveness and usefulness is validated.

Key words: wireless locating, application framework, Ultra Wide Band（UWB）, coordinates transformation, Object-oriented Graphics Rendering Engine（OGRE）

摘要： 目前无线定位应用程序存在结构不统一、无法兼容多种定位设备的问题。应用开发框架对应用程序中的共性部分进行抽象，可以提高软件复用，缩短开发周期。设计了一个无线定位应用开发框架，支持多种定位设备数据的融合，实现了业务逻辑与底层定位平台的隔离，标准化了无线定位应用程序的体系结构。同时，给出了该框架的一个应用实例，介绍了其中的关键技术，验证了该框架的有效性和实用性。
